Objects of persons in a vehicle are detected with a sensor. The data of the sensor signal or evaluated sensor data are transmitted to a remote control unit for an occupant protection system. The sensor data are in addition stored in a device comprising the sensor if the control unit indicates that an impact has been recognized.

Device and method for sensing an object or a person in the interior of a vehicle and vehicle occupant protection apparatus in a vehicle with such a device

In order to sense an object or a person in the interior of a vehicle, a laser emits a laser pulse. The laser pulse which is reflected at an object or a person is registered and evaluated. The energy content of a following laser pulse is determined based on a characteristic variable of the reflected laser pulse such as its power or its energy content.

Method and device for sensing and object or a person in the interior of a vehicle

In order to sense an object or a person in the interior of a vehicle, laser pulses are output by a laser. Sensing devices are provided for sensing a characteristic variable that is decisive for the transmission energy of the laser. The transmission energy is reduced or the emission of a laser pulse is prevented as a function of the sensed characteristic variable.

Device and method for sensing an object or a person in the interior of a vehicle

A sensor which is installed in a vehicle, for sensing an object or a person, is operated for adjustment purposes in a test mode. The installation position of the sensor or of the device in the vehicle is changed with an adjustment device as a function of the evaluation of the test data which are determined. Alternatively, or in addition, a message can be issued as a function of the result of the evaluation. The invention ensures that the device is installed at a precise location in the vehicle and the position of vehicle occupants is thus determined precisely.

Device for sensing an object or a person in the interior of a vehicle and method for operating such a device

A sensor for detecting an object or a person in the interior of a vehicle consumes a first average power in a normal operating mode. The power supply for supplying the sensor is monitored. The sensor is operated with a second average power which is reduced in comparison with the first average power if the power supply is considered as no longer being sufficient for the normal operating mode.
